Abstract:Zhejiang Jingyuan Membrane Technology Co., Ltd. and Zhejiang Fuchun Ziguang Environmental Protection Co., Ltd. and Tongji University Architectural Design and Research Institute (Group) Co., Ltd. recently studied the application of high-efficiency PTFE immersion ultrafiltration process in steel wastewater treatment. Signed a technology development contract.

Zhejiang Jingyuan Membrane Technology Co., Ltd. (hereinafter referred to as "Net Source Technology") and Zhejiang Fuchun Ziguang Environmental Protection Co., Ltd. and Tongji University Architectural Design and Research Institute (Group) Co., Ltd. recently "efficient PTFE immersion ultrafiltration process in steel The Applied Research in Wastewater Treatment signed a technology development contract.

Zhejiang Fuchun Ziguang Environmental Protection Co., Ltd. is a subsidiary company of Hangzhou Steel (600126), which is committed to the development of domestic environmental protection water and related industries, in urban sewage treatment, industrial wastewater treatment, municipal water supply, environmental protection equipment integration, sludge Has accumulated a large number of advanced technology and project management experience in the field of processing, has strong investment and financing capabilities, rich project operation experience, professional technical management team and complete industry qualification certificate, and has 30 wholly-owned subsidiaries and shareholding companies. The water treatment project has a scale of 2.55 million tons/day and has operations in Zhejiang, Jiangsu, Hubei, Anhui, Henan, Fujian, Gansu and other provinces and cities. It is the largest water investment and environmental protection enterprise in Zhejiang Province.

Tongji University Architectural Design and Research Institute (Group) Co., Ltd. Tongji University Architectural Design and Research Institute (Group) Co., Ltd. is a well-known large-scale design unit of group management. Holding a number of design qualifications and engineering consulting certificates issued by the State Construction Administration, it is one of the most widely designed design units in China.

In 2016, Net Source Technology and Zhejiang Fuchun Ziguang Environmental Protection Co., Ltd. jointly undertook the sewage deep treatment project of Ningbo Iron and Steel Co., Ltd. Since the immersion ultrafiltration system of Ningbo Iron and Steel Co., Ltd. sewage treatment project has been put into use since its acceptance, the system has been running stably. The indicators include water quality, water production, flux, transmembrane pressure difference and other technical indicators, as well as electricity consumption and drug consumption economic indicators. Meet the contract assessment requirements.

Under the premise of smooth cooperation in the early stage, the common concept of “breaking international monopoly, filling domestic gaps and leading the international frontier with technological innovation” has prompted the three parties to further reach their cooperation intentions, actively exert their respective advantages, and continue to promote “2025 Made in China” and dig deeper. The performance of the independent innovation brand PTFE hollow fiber membrane enhances the original design operation efficiency of the submerged ultrafiltration of Ningbo Iron and Steel Co., Ltd., and achieves the effect of energy efficiency and energy conservation. At the same time, it promotes the development of domestic independent innovation membrane industry and enhances the strength of domestic national innovation brand.

Through cooperation, the three parties cooperated to study the application of PTFE immersion ultrafiltration process in steel wastewater treatment, and further explored various properties of PTFE hollow fiber membrane in steel wastewater treatment, so as to improve the overall operation performance of immersion ultrafiltration and achieve energy saving. The purpose of the effect. By changing the existing operating conditions, Netsource Technology comprehensively considers and evaluates the overall performance of the membrane system, continuously improving product performance and technological leadership; Zhejiang Fuchun Ziguang Environmental Protection Co., Ltd. as a leading company in the water industry will further explore in steel Advanced technology and project management experience in wastewater treatment and industrial wastewater treatment membrane engineering applications; Tongji University Architectural Design and Research Institute (Group) Co., Ltd. collates and analyzes the actual operation of the system and recorded data to obtain an optimal Run the parameters and produce an objective and fair operational research report. Therefore, the design standards and operation specifications of PTFE hollow fiber membranes in steel wastewater are established, and demonstration and promotion and application are carried out in the industry, creating value for more industrial enterprises and boosting the development of China's environmental protection industry.
